Abstract (en)
[origin: WO2011004286A1] The invention refers to a multifunction sensor system and a corresponding method for supervising room conditions, comprising a temperature sensor, a humidity sensor, an ultrasonic transducer for emitting ultrasonic waves and being positioned in a fixed distance to a reflecting fixed reflective surface. For calculating the CO2 concentration in the supervised room, the time of flight of ultrasonic waves between the transducer and the fixed reflective surface is measured, and the CO2 concentration is calculated from the output values of the temperature sensor, the humidity sensor and the measured time of flight.
